One of our data entry people could not purge a file; when I looked at the group, this is what I found: 

********************

The data entry operator has AL,GL capabilities; her lead was able to purge the file but not her and she claims to have been the creator.

I have set the access equal (R,W,A,L,X,S:ANY) but am wondering how this got "unset".
No one I know of would have had cause or even know how to set the permissions.

While it is possible, the application written in SPL might have changed this, it is doubtful.

This is the only time we have seen this.

We are on 6.0 Express 2+ and no changes have been made to the system since mid February when we last rebooted.

Any thoughts?
